The first question is if you want to design anything on the TT platform. If the answer is no, then don't take the course.

If you're open to TT, AND you are an advanced trader, AND you want to build some automatic trading sequences, then the course would probably be appropriate. By advanced traders I mean you have systematic but manual models you are looking to automate. The course is not about how to trade, but how to automate existing models or testing new models.

The algos they teach you to build are more algos designed to get best possible price on a fill, e.g, if you have 100k shares to fill, but you want to release orders without showing your book to the market, how does the algo release the orders? How many at at time? Is there a time delay? Is there an iceberg that you are creating? Do you chase the market?

Highly NOT recommended if a technically challenging course is going to be a waste of money.

Highly recommended if you currently have no automation and need to learn about how to automate and possibly what questions to think about in the automation process, and one tool to explore automation.
